Step 3: Heating and bending

Step 4: Some finished shapes

These are a few bent pieces of pipe. The ends of the pipe are still taped.

Step 2: Fill the pipe with sand

Cover one end of the pipe with masking tape to hold the sand in. Fill the pipe with sand, tapping the taped end of the pipe on the ground to compact the sand inside. When the pipe is full of compacted sand, tape over the top end. You are ready to heat and bend.
